220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2026)

According to the CompTIA A+ Core 1 (220-1201) virtualization objectives, a Type 1 hypervisor is known as a bare-metal hypervisor because it installs directly onto the physical hardware of a system rather than running on top of a traditional operating system. This architecture allows the hypervisor to manage hardware resources—such as CPU, memory, storage, and networking—without the overhead of a host operating system. Because of this direct interaction with the hardware, Type 1 hypervisors typically provide higher performance, better scalability, and improved stability compared to Type 2 hypervisors.

Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V (bare-metal deployment), and Citrix XenServer. These hypervisors are commonly used in enterprise data centers, cloud infrastructure, and large virtualization environments where multiple virtual machines must run efficiently on a single physical server. 🖥 ️

Option A (Host OS required) describes a Type 2 hypervisor, such as VMware Workstation or Oracle VirtualBox, which runs on top of an existing operating system. Option C (Lightweight OS) may describe some hypervisor environments but is not the defining characteristic. Option D (Local configuration options) is also not specific to Type 1 hypervisors.

Therefore, the key characteristic that defines a Type 1 hypervisor is that it performs a bare-metal server installation directly on the hardware

The correct answer is B. Secure Boot.

According to CompTIA A+ Core 1 220-1201 objectives under Security:

Secure Boot is a UEFI firmware feature that ensures a computer boots only with software that is trusted and digitally signed by the manufacturer.

This prevents malicious or unauthorized bootloaders and operating systems from loading, protecting the system from rootkits and other boot-time attacks.

Secure Boot does not require disabling USB devices; it simply checks that any bootable device contains a signed operating system.

Why the other options are incorrect:

A. BIOS password: Protects access to BIOS/UEFI settings but does not verify trusted software during boot.

C. USB settings: Can control USB access but cannot enforce boot validation for signed OS or prevent unauthorized boot devices.

D. Single sign-on: Provides authentication convenience for users, unrelated to boot security.

The correct answer is D. Decreased burn-in.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.

Unlike OLED displays, which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.

Why the other options are incorrect:

A. Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.

B. No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.

C. Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.

The correct answer is A. 2.4GHz.

In the CompTIA A+ Core 1 220-1201 networking objectives, wireless networking technologies include frequency bands such as 2.4GHz, 5GHz, and 6GHz, along with related concepts like channels, regulations, channel selection, Bluetooth, 802.11 standards, NFC, and RFID.

The 2.4GHz band supports the most devices because it is the oldest and most widely adopted Wi-Fi frequency listed. Many legacy devices, including older laptops, printers, IoT devices, smart home devices, and wireless peripherals, still rely on 2.4GHz. It also has better range and wall penetration than higher-frequency bands, although it is usually more crowded and slower.

Why the other options are incorrect:

B. 5GHz

5GHz is newer than 2.4GHz and generally provides faster speeds with less interference, but it does not support as many older legacy devices.

C. 6GHz

6GHz is the newest Wi-Fi frequency option used with newer Wi-Fi standards, so it has the least legacy device support among the Wi-Fi frequency choices.

D. NFC

NFC is a short-range communication technology, not a Wi-Fi frequency band. It is used for close-proximity functions such as tap-to-pay, pairing, and access cards, so it is not the best answer.

Final Answer: A. 2.4GHz

The correct answer is A. RJ11.

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

RJ11 connectors are commonly used for telephone lines and data cables that use two pairs of wires (four wires total).

This connector is standard for analog telephone connections and DSL connections.

Why the other options are incorrect:

B. F-type: Used for coaxial cables, commonly in cable TV or broadband internet, not for two-pair data cables.

C. ST: A type of fiber optic connector, not used for copper two-pair wiring.

D. Molex: Primarily used for power connections in computer hardware, not for network or phone cabling.

The correct answer is B. Elasticity.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud Concepts:

Elasticity refers to the cloud computing capability to automatically allocate and deallocate resources based on current demand. This ensures that applications have the necessary compute, storage, and network capacity during peak loads, and resources can be scaled down when demand decreases, optimizing efficiency and cost.

Why the other options are incorrect:

A. Hybrid deployment: Refers to using a combination of public and private clouds; it does not describe dynamic resource allocation.

C. Multitenancy: Describes the architecture where multiple users share the same infrastructure securely.

D. Metered utilization: Refers to charging based on resource consumption; it is a billing mechanism, not a dynamic allocation feature.

The correct answer is D. SMTP (Simple Mail Transfer Protocol).

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

SMTP is the standard protocol used to send emails from a client to a mail server or between servers.

POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol) are used for receiving emails, not sending them.

LDAP (Lightweight Directory Access Protocol) is used for accessing and managing directory services, such as authentication and organizational information, not for email transport.

The correct answer is A. Virtual LAN (VLAN).

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

VLANs are used to segment a physical network into multiple logical networks. By assigning the accounting department to a separate VLAN, users on other VLANs cannot access its network traffic without routing, thereby isolating sensitive departments while using the same physical switch.

VLANs improve security, reduce broadcast traffic, and allow network administrators to enforce access controls at the layer 2 level.

Why the other options are incorrect:

B. DHCP reservations: Ensure that specific devices always receive the same IP address, but do not restrict network access.

C. Content filtering: Controls web or application traffic based on content, not segmenting network access between departments.

D. Port security: Limits which devices can connect to a port but does not provide full network segmentation for an entire department.
